no just as long as its 6 volt. if you plug your lamp in a 22ah or an 8hr it will just last longer providing there both 12 volt the only other way is to decrease the draw from the motor
aye but its a bit different a motor to a bulb lol. Don't like the sound of reducing the draw of the motor, it's slow as it is right, that 20ah one looks good, it's just whether it'll f***ing fit under the seat lol. Where did you find that mate? I was just going to pm you with this question, wish I had now
